摘要
The lasing operation of three-quantum-well GaInNAs stripe geometry lasers grown by MOCVD on 0 degrees and 6 degrees misoriented (100) GaAs substrates, respectively, hale been demonstrated and their performance is compared for the first time. Both devices achieved room temperature, pulsed lasing operation at an emission wavelength of 1.17 mu m, with a threshold current density of 667 A/cm(2) for lasers grown; on 6 degrees misoriented substrates, and 1 kA/cm(2) for lasers grown on 0 degrees misoriented substrates, The threshold for the lasers grown on 6 degrees misoriented substrates compares favorably with the best results for GaInNAs lasers, Lasers with narrower stripe width and a planar geometry have also been demonstrated by the use of lateral selective wet oxidation for current confinement, with a threshold current density of 800 A/cm(2) for 25-mu m-wide devices.
